I would be afraid to fly in the day of the cruise. We always arrive early and spend the night and get up early the next morning refreshed and ready to go. I use yapta.com where I type in the flight I want and they let you know when it reaches the price you want to pay. Beings you have awhile might be worth downloading it and put in some flights your interested in. I have 10 on tap for Puerto Rico in February. When the best price comes up I will book it. Flights change prices daily. On Thursday one was $233.10 pp from California to PR and by the next day it was $310.00. Someone in here told me about it.
